The rotating of a lot makes a lot of sense, I think it is after I had moved a lot, not from the library, but from another lot in the same game. I had moved a garden from one lot that for some reason had the grass covering the road, which was really irritating to see as I was working on the garden, creating it. I moved it to another lot and had rotated it get the gate on the side I wanted it to be.
I didn't use the testingcheat until after I had moved, to do some work (moveobjects) on the garden, so that couldn't have been a factor.
After I had moved the garden, then typed in the cheat, then typed in the moveobjects and buydebug cheats, that is when I saw the multiple boxes.
So, that could be the reason.
